When you dig into your meal or grab a quick bite on the way to work, the food you eat goes toward fueling your body. As your favorite (or not so favorite) foods pass through your digestive system, your body absorbs nutrients and uses them to power you through your daily routine. The remaining waste heads out through your bladder or intestines. It's a good system.

Some years ago, NASA bred wheat in space with the goal of providing an unending food supply for astronauts. To help the plant along, astronauts shined light on the plant continuously. As far as the crop was concerned, the sun never set. It was always noon on a cloudless day. The extra light fueled its rapid growth.
This June 2017 swarm of 117 drones set the world record for the most fixed-wing drones in a single swarm.
The garbage that seagulls had been eating included rubber bands, plastic bag shreds, chunks of Styrofoam, and wax paper from coffee cups.
How will the universe end? Will it sputter out in a realm of ice, cooling continually as it expands until it reaches the absolute zero of temperature throughout its vast expanse? Will it die in a fiery blast as its component parts rush together faster and faster until they all meet in an enormous fireball? Or will the cosmos live on forever, expanding and contracting in relentless succession?
Prior to the night of August 10, 2017, I harbored an unabashed love for lobster mac and cheese. I realize that undercooked pasta and cheddar sauce are no real place for delicate crustacean meat, but I longed for it anyway—because there's only one restaurant I know of where I can eat it. Or at least I could, before that evening.
When I looked at my appointment book for the day, I thought something must be wrong. Someone who worked in the fitness industry was bringing his cat in to the Tufts Obesity Clinic for Animals. Did he confuse us for a different kind of weight management clinic? Is he looking to get muscle on his cat or maybe kitty protein shakes?
Though it sounds like a factoid ripped straight from Ripley's Believe It Or Not, experts confirmed that Jacksonville, Florida really was colder than Anchorage, Alaska on Tuesday. With strange weather fronts and severe storms blowing across the country, the biggest city in the frigid “Last Frontier” state hit 49 degrees. Meanwhile, parts of the so-called “Sunshine State” only eked out a high around 41 degrees.
Heading to the US to escape Australian heat? You're going from one extreme to the other. With snow falling in Florida and temperatures along the East Coast dipping well below zero, the need for a good winter jacket has never been greater. The warmth from your body wants to get out into the cold atmosphere—that's just simple thermodynamics—but a good jacket can keep it from escaping, even when the temperatures hit “polar vortex” or “bomb cyclone” levels of frigidity.
Ryan Knapp is a senior staff meteorologist and weather observer at the Mount Washington Observatory in White Mountains, New Hampshire. When we talked on the phone, the temperature at the observatory—which is at the mountain's summit— was hovering between -20 and -30 degrees. Most of us experience painfully frigid temperatures like that rarely, if ever, but it's not out of the ordinary for Knapp and the Mount Washington crew.
